### Description

Hadronic resonances can act as useful probes to examine the hadronic phase in ultra-relativistic heavy-ion collisions. On the other hand, there could also be perspectives and unexplored methods for studying the partonic phase via resonances. Properties, such as the masses and widths, of resonances produced or decaying during the partonic phase could be modified.

In order to reach resonances from the partonic phase, resonances' properties as a function of emission direction with respect to high transverse momentum particles (~ jet leading particle) should be investigated.

In this contribution, the study of the mass and width of the resonances $K^{*}(892)^{0}$ and $\phi(1020)$ in lead-lead collisions at $\sqrt{s_\mathrm{NN}}$= 5.02 TeV with respect to the leading jet particle will be presented and the influence of the background (thermal resonances) will be shown.
